when having reached itslimit of climb will f destroy the heavier part ot the frame, and

Cil

so be tree of danger to persons beneath the Vpoint from which the parts of the rocket would fall.

A' further object of the invention is to provide av form of rocket with a plurality of chambers arranged on the sameplane, the chambers tilled with suitable explosive material tor lifting therocket while. burning, with holes in the sides and bottom of the chambers both tor lighting and turning the rocket by means otV burning gases escaping tromthe holes while the material is being" burned; together with other chambers containing matter for pyrotechnic display as stars, or flags or other signals to be discharged from the chambers whenvthe rocket reaches substantially its highest point, and a third set of chambers for carrying a ldestructive explosive tor destroying the heavier parts of the rocket frame after the liberation of the display contents, withv fuse connection between the several lifting chambers, and display chambers and destructive chambers, so arranged that the several contents ot the various, chambers will be fired, or discharged at predetermined periods as may be desired. l: have illustrated my invention by the accompanying drawings, of which f- Figure 1 represents a top plan ot' the rocket; Y

Figure 2 in section. K

Fig. 3 represents a detail ot -a chamber for carrying display matter.

Like numerals on Vdifferent figures represent like parts.

Numerals 1 and 2 indicate'a short section or round wooden rods with a mortice connection 3 at their centers as they are connected or held'together by glue or other simple means to form right angles to each other, with the iour ends thereof .pointing in opposite direpresents a side elevation partly n rections, and on which ends the lifting chambers are mounted. A pivothole 4 is providedthroughthe centeror axis of the crossed rod, for holding the rocket on a suitable pivot pin, and above the ground or tiring` platform while the. same is ignited, and

to permit the rocket to revolve in horizontal position before its vflight is begun.

5, (5, 7, and 8, are cylinders ot' any desired dimensions for carrying the lifting andrevolving charges of explosive, which may be o1" saltpetre, sulphur and charcoal, or other suitable steadily burning explosives compressed into the Vchambers of the cylinders or tubes so as to support a steady combustion, but preferably o'li` a faster burning composition than is used in ordinary one chamber straight rockets. One end'of earch tube is slipped on and over a respective end ot the rods 1 and?l and suitably secured thereto. Adjacent the position oi the ends ot the rods in the tubes a clay partition 9 is provided for holding the chargein the tubes respectively, and similar vclay partitions 10 are provided at the outer ends of the tubes for holding said contents of the tubes after the same have been securely tamped into the respective chambers. n Each tube has a hole 11 near its outer end and on one side thereof, a pluralityof holes shown as 12 and 13 opening through their bottoms, and across each end may be cut a notch 14, and a connecting quick match fuse 15 is carried` over the notches or otherwise held near the ends of each tube with projections therefrom 15a for ignition by operation', other-,suitable branches or sections 1(3 are extended into each of the holes 11 for igniting the charges in the tubes, and these extensions ot the fuse 16 are carried into the holes 12 and 12S-and for igniting the charge in the tubes at such new points, all of the contacts from the fuse 15 being ignited at practically the same moment.

17 and 17 represent'a'ny size or desired form ot containers for carrying display matter; 17a such as brilliant burning colors of various shades, or flags etc. for signals or for pyrotechnic displays for public celebrations, and are tired by respective fuses 18 and 18 which Contact with and are ignited by the burning contents of the tubes 6 and 8 when the tire reaches the points ot contact beneath the holes 19 through which the fuses 18 enter; and this ignition and biusting ot' the containers 17 will take place land 2 or the other means used for connectiov rocket, 1^

near the. top of theline of travel ofthe i` 2O and 2O represent any sizes vorformsrof 'containers desirable for carrying charges of explosives of sufficient-power to shatter theircontainers and particularly the holding rods ing the tubes 5, 6, 7, and 8, whichexplosive `may be also of brilliant burning vcolors for A additionaldisplay as well as for. shattering Athe partsofth'e rocketV into small fragments which willnot injurev the persons beneathV anden whom theymay fall. Fuses 21 connect the containers with thel contents of 1 'the tubes 6 and f7 through holes 22 at a point adjacent the. inner clay abutments, and will l'therefore not become ignited until the lifting power from the burningcontents of tubes has become practically exhausted; the holes 22 being nearer the abutments Vthan the holes19 'so the part-s will not be shattered until. after thebursting ofthe containers 17.

With this form of rocket the danger from 'falling guide sticks and large parts of rockets isv eliminated, and a much greater display is given, not only from the bursting .of the plurality of chambersll'? and 20but from the great amount of fire that flows out from the'holes 11,12, and 13 as the'rocket rises, and -a greater roar and sound is produced'.

n wiii be,V understood um' when the` i charges are Afired by the ignition from the fuses through the holes 11,-12, and 13 that l the expulsion ofthe gases first from the holes 1l Iwill cause the rockettorevolve, followed .almost immediately by thel expulsion of the ,C iasjesandY lire from thebottom holes 12 and 1,3: which causefthe rocket to rise, to such zhei-ght'as maybe determined by the sizes of f the containers and contents 'thereof'.l The i holes 11, 12, andV 13 arepreferably equal dis-` tances from eachother as the charges in the tubes burn inl each direction, while the hole ...13.is spaced-half the distance from the abut- Y ment 9 to whichthe burning is in only one,

fuse l5 tothe ignition and exhaust holes 11,

12,. and 13 only in the tubes 5 and? with auxiliary fuses connecting the holes 12 in tubes 5 and 7 with the holesg11', 12 and 13 in lthe tubes 6 and 8, and in this method' of fuse ried vmuch higher.

contact theirocket would be raised by the burning ofthe charges first in tubes 5 and 7 followed 'by the burning of the contents of tubes 6 and 8,' and the rocket thereby caradded to the four shown, with similarA fuse connections' for simultaneous or alternate Additional tubes may be ignition. In either form the rocket rises with a circular motionscattering the ex' y haustedv gases in aV whirling cloud, or body of fire VThe central holding frame may be VformedY of papier mch or other light inaterial instead of the rods shown as 1 and 2.

Vhile for purposes of illustration in the! drawings l have shown the holes 19 and 22 I in line on top of the chambers, in practice, it

is advisableto have Vthe holes 19, 19 to enter Y the chambers from one side thereof,.to avoid danger of igniting the fuses 21by the burningof` fuses 18. I

For the colors in the signal containers any well known compositions may be used, suchv L as barium nitrate, sulphur and perchlorate of potash for` green etc; and for the explosive containers, may be. used any well known composition therefor orv aluminum, sulphur. Y and saltpetre.
